Students wanted to see if the distance the marble rolled down a ramp changed the force it had. They allowed a marble to roll down the ramp from different starting points and strike a second marble. To determine if the force of the rolling marble changed, what should the students measure?

• The distance marble #2 moves after being struck by marble #1.

• The time it takes marble #2 to move after being struck by marble #1.

• The direction marble #2 moves after being struck by marble #1.
